[0045] 在本发明的实施例中,待测样品26 (例如珠串)被放置于承载表面211之上而光学探头22从下方将激发光通过承载表面211上的出光孔212、213照射到待测样品26。 [0045] In an embodiment of the present invention, the sample 26 (e.g., beads) is placed on the bearing surface 211 and the optical probe 22 from below the excitation light irradiated by 212 and 213 carrying the aperture 211 on the surface 26 sample to be tested. 与传统的将光学装置放在待测样品上方的方式相比,该一方面能够避免光学装置妨碍取放待测样品26,另一方面也使得光学探头22的出光口与待测样品26可W保持稳定的距离,例如可W使得激发光的聚焦位置位于出光孔212、213附近,该可W准确地保证待测样品26的多次测量、多个待测样品26的测量W同样的照射光强进行,而不需要每次调整光学探头22与待测样品26的相对位置,从而易于抑制由于测量一致性问题造成的误差。 Compared to the sample to be tested is placed upward with the conventional optical device, the optical device can be avoided on the one hand take place interfere with the test sample 26, on the other hand so that the optical probe and the test sample light outlet 22 may be 26 W stable distance, for example, such that the focus position W located in the vicinity of the excitation light of the light holes 212 and 213, which can ensure accurate W plurality of measurements of 26 test samples, the test sample is measured a plurality of the same 26 W of irradiation light be strong, and not the relative position of the optical probe 22 and the sample to be tested need to 26 each adjustment, thereby easily suppressing the measurement errors due to problems caused by the consistency. 而且,由于不需要每次调整光学探头22与待测样品26的相对位置,该珠宝玉石鉴定设备20易于应用于对成串的待测样品26的快速检测,例如,对于珠串,只需要在承载表面211上移动珠串,使珠串上的珠子依次置于出光孔212、213处,即可实现对珠串中的每个珠子的快速检测。 Further, since it is unnecessary to adjust each position of the optical probe 22 relative to the test sample 26, the identification device 20 jewelery be readily applied to the rapid detection of the test sample 26 clusters, for example, for the beads, only the moving the carrier beads on the surface 211, so that the beads are sequentially disposed on the beads of the light holes 212 and 213, can achieve rapid detection of the beads in each bead.

[0046] 作为示例,光学探头22的光学系统可W由光学分立元件构成,或者,光学探头22 可W为光纤探头。 [0046] As an example, the optical system of the optical probe 22 may be an optical element constituted by a separate W, or W optical probe 22 may be an optical fiber probe. 作为示例,光学探头22可W包括激光源,或者激光源也可W与光学探头22是分立的。 As an example, the optical probe 22 may comprise a laser light source W, or W may also be a laser source of the optical probe 22 is discrete. 在一示例中,所使用的激光波长可W是785nm,也可W采用其它波长。 In one example, a laser wavelength of 785 nm is used may be W, W may be employed other wavelengths. 作为示例,光学探头22也可W包括必要的控制模块,例如用于激光驱动和控制的模块,或者,该控制模块也可W设置于光学探头22外部,例如设置在数据处理装置中。 As an example, the optical probe 22 may also include necessary W control module, for example, drive and control module for a laser, or the control module may also be provided on the outer W optical probe 22, for example set in the data processing apparatus.

[0048] 作为示例,如图1-2所示,珠宝玉石鉴定设备1还可W包括防护挡板23和承载防护挡板23的滑轨24。 [0048] As an example, shown in Figure 1-2, jewelery identification apparatus 1 may further include a protective shield 23 W and the carrier 23 of the protective shield 24 slide. 所述防护挡板23位于所述承载表面26上方并能够沿所述滑轨24在竖直方向上滑移。 The protective shield 23 is located above the bearing surface 26 and capable of sliding along the rail 24 in the vertical direction. 在一示例中,防护挡板23可W安装于移动滑块25上,并通过移动滑块25 与滑轨24实现可滑移地连接。 In one example, the protective shield 23 may be mounted to the W movement of the slider 25, and slidably connected to achieve by moving the slider 25 and the rail 24. 所述防护挡板23用于在进行检测时在承载表面211的上方遮住出光孔,W免激发光伤害到操作者的眼睛。 The protective shield 23 for the bearing surface 211 of the cover above the hole during the light detection, W Free excitation light damage to the operator's eyes.

[0049] 在一示例中,所述出光孔212、213的直径是可缩放的。 [0049] In an example, the diameter of the aperture 212 and 213 are scalable. 对于珠宝玉石而言,其不同的局部可能具有不同的成分差别,因此,有时需要对待测样品26的某个小的局部进行特别检测。 For purposes of jewelery, which may have different local differences in different components, and therefore, may need to be treated to a small local special test sample 26 is detected. 为了精确地将激发光引导至所期望的待测样品26的局部而避免待测样品26的其它部分对检测结果的干扰,可W缩小出光孔212、213的直径。 In order to precisely localized excitation light to a desired test sample 26 while other portions of the test sample 26 to avoid interference with the detection results, W may be a reduced diameter aperture 212 and 213. 而当需要对待测样品26的更大的局部进行检测时,可W扩大出光孔212、213的直径使更多的激发光到达待测样品26 W避免光强损失和提高信噪比。 When a larger sample to be measured local needs 26 is detected, W can expand the diameter of aperture 212, 213 so that more of the excitation light reaches the sample to be tested 26 W to avoid loss of light intensity and to improve the signal to noise ratio.

[0050] 如上所述,出光孔212、213可W有一个或更多个。 [0050] As described above, the light holes 212 and 213 may have one or more W. 例如,所述承载表面26可W具有第一出光孔212和第二出光孔213,分别对应于第一测量位置和第二测量位置,所述载物台21能够相对于光学探头22在水平方向上移动使得所述光学探头22所对应的测量位置在第一测量位置和第二测量位置之间切换。 For example, the bearing surface 26 may have a first light-W hole 212 and the second light hole 213, corresponding to the first measurement position and the second measurement position, the stage 21 can be in the horizontal direction with respect to the optical probe 22 22 such that the moving position of the corresponding measured optical probe switched between a first position measurement and the second measurement position. 该意味着当预先将不同的待测样品26放置于不同的出光孔处(例如第一、第二出光孔212、213)则可W通过载物台21的平移来切换对于不同的待测样品26的检测,而不必逐个地移动待测样品。 This means that when different test sample previously placed in 26 different light holes (e.g. a first, a second light holes 212 and 213) may be W by translation stage 21 is switched for the different samples to be tested 26 detection, one by one without having to move the test sample. 该对于提高快速检测的效率很有帮助,特别是设置有比较多的出光孔的情况。 This is helpful for improving the efficiency of fast detection, more in particular a case provided with a light hole. 例如可W在载物台21沿平移方向的两侧上进行待测样品26的装载/卸载,而利用载物台21的往复平移来逐个切换待测样品26 W提高效率。 W can be, for example, on both sides of the test sample 21 in the loading direction of translation stage 26 in the loading / unloading, utilize reciprocating translation stage 21 is switched to the test sample-by-26 W efficiency.

[0064] 相似度的计算有多种方法。 [0064] There are various methods of calculating the similarity. 例如,假定待测样品的拉曼光谱曲线函数为A(X),标准拉曼光谱曲线函数为B(X),在一示例中,可W通过式(1)对两者的相似度进行计算: For example, Raman spectral profile as a function of sample to be tested is assumed that A (X), a standard Raman spectrum curve function B (X), in one example, W can be calculated by the similarity of the two formulas (1) :

[0071] [0071]

Figure CN104749158AD00092

[0072] 上述相似度计算可W针对整个拉曼光谱曲线进行,也可W仅针对于拉曼光谱曲线中具有特征部分的局部进行。 [0072] The similarity calculation can be performed for the entire W Raman spectrum curve, W may only be partially directed to the characterizing part of the Raman spectrum curve. 对于上述步骤700中另一待测样品的拉曼光谱曲线函数和标准拉曼光谱曲线函数的相似度的计算,与上述待测样品的拉曼光谱曲线函数和标准拉曼光谱曲线函数的相似度的计算基本相同,在此不再费述。 For calculating the similarity of the Raman spectrum and the standard Raman spectrum curve function curve function according to another sample to be tested in the above step 700, and the curve function and the standard Raman spectrum of the sample to be measured Raman spectral profile similarity function the calculation is basically the same, which is not described charge. W上仅是给出了一些相似度计算的示例,本领域技术人员所知的一些其他的相似度计算方法也是可行的。 W is only given on some examples of similarity calculation, the similarity calculating some other method known to the skilled person are also possible.

[0073] 对于待测样品的拉曼光谱曲线函数和标准拉曼光谱曲线函数的相似度,如果其超过预定的阔值,则可W判定待测样品的成分与标准拉曼光谱曲线所对应的样品的成分一致W完成对于待测样品的鉴定。 [0073] Raman spectrum of a similarity function curve sample to be tested and the standard Raman spectrum curve function, if it exceeds a predetermined value width, W may be determined corresponding to the standard component and the Raman spectrum curve of the sample to be tested the same components of the sample W is completed sample to be tested for identification. 相反,如果其低于预定的阔值,则可W判定待测样品的成分与标准拉曼光谱曲线所对应的样品的成分不一致。 In contrast, if it is below a predetermined value width, W may be determined with a standard sample composition component measured Raman spectral profile corresponding to the sample is inconsistent. 该预定的阔值可W根据实际的检测需要、 检测仪器的精度等因素来给出。 The width of the predetermined value W may be given according to the actual needs of the detection, the detection accuracy of the instrument and other factors.

[0074] 如图所示,步骤400还可W包括在上述步骤403之前的两个可选的步骤,即; [0074] As shown, in step 400 may further comprise two W optional step prior to the above step 403, i.e.,;

[0075] 步骤401 ;从所述拉曼光谱曲线中搜索一个或更多个特征峰;W及 [0075] Step 401; from the Raman spectrum graph search for one or more characteristic peaks; and W is

[0076] 步骤402;计算所搜索到的特征峰的峰位与峰宽,并将所述峰位与峰宽与标准拉曼光谱曲线中的特征峰的峰位与峰宽对比W对需要在步骤403中进行计算的标准拉曼光谱曲线进行预筛选。 [0076] Step 402; calculating the searched peak position and the peak characteristic peak width and the peak position and peak width of the characteristic peaks of the Raman spectrum of a standard curve with the peak contrast value width W of the need to standard calculated in step 403 prescreening Raman spectrum graph.

[0077] 由于珠宝玉石种类繁多,在对珠宝玉石的鉴定中,可能需要将待测样品26的拉曼光谱曲线与多种标准拉曼光谱曲线分别进行对比。 [0077] Since a wide range of jewelery, the identification of jewelery, it may be necessary to test sample 26 Raman spectrum graph of Raman spectroscopy with multiple standard curves were compared respectively. 如果对于每种标准拉曼光谱曲线都进行相似度计算,则可能导致计算量较大。 If the Raman spectrum for each standard curve are calculated similarity, it may cause a large amount of calculation. 而借助于上述步骤401、402,可W通过峰搜索和峰筛选排除掉与待测样品26的拉曼光谱曲线差异明显的标准拉曼光谱曲线,从而减小步骤403中的计算量。 With the above steps 401, 402 and may be W and a peak by peak searching and screening test sample excluded significant difference curve 26 is the standard Raman spectrum of the Raman spectrum graph, thereby reducing the amount of calculation in step 403. 对于特征峰的搜索W及峰宽和峰高的计算,例如可W利用拉曼光谱曲线中的峰信号统计分布估计出两个高低阔值,在搜索过程中,当信号幅度大于高阔值,认为找到峰,并向前向后找到小于低阔值处认为是峰起始和结束点,进而计算峰高、峰宽等参数。 W searches for peaks and calculate peak width and peak height, for example, using a peak signal W statistical distribution curve Raman spectrum to estimate the level of two width values ​​in the search process, when a signal of high amplitude is greater than the width value, We found that the peak and width less than the low forward backward found that the peak value of the start and end points, then calculate the peak height, peak width and other parameters. 但本发明不限于此,其它的能够进行特征峰的搜索W及峰宽和峰高的计算的方法也是可行的。 However, the present invention is not limited thereto, and can be other characteristic peak search and peak width W and height calculation methods are possible.

[007引另外,作为示例,在待测样品26的拉曼光谱曲线的特征峰比较明显的情况下,在实际中,相似度计算甚至可W简化成搜索待测样品26的拉曼光谱曲线中是否在某一个或更多个位置上存在与标准拉曼光谱曲线的特征峰相对应的特征峰来直接进行确定。 [007 cited Further, as an example, characteristic peaks in the Raman spectrum of the sample to be measured curve 26 more obvious case, in practice, the similarity calculation can be even reduced to searching test sample W 26 Raman spectrum of curve whether there is a standard Raman spectrum curve in one or more positions corresponding to characteristic peaks characteristic peaks determined directly.

[0080] 而在另一鉴定示例中,图7示出的鉴定结果表明待测样品的拉曼光谱曲线与聚苯己帰塑料的标准拉曼光谱曲线相一致,该表明该待测样品为由聚苯己帰塑料制成的伪仿品。 [0080] In yet another example, the identification, the identification results are shown in FIG. 7 indicates that the test sample with a standard curve of a Raman spectrum of polyphenylene kaesa plastic has a Raman spectrum graph consistent, indicating that the samples to be tested by the polyphenylene hexyl kaesa dummy imitations made of plastic.
